Abstract

The invention discloses a method, a device and a system for increasing the uplink rate. A base station sends measurement configuration information to user equipment through a first carrier so that the user equipment can use a configured uplink sub-frame to send an uplink measurement signal periodically, wherein the configured uplink sub-frame is included in an uplink sub-frame set which can be transmitted on a second carrier. When judging that the signal quality and / or signal intensity of the uplink measurement signal received within a predetermined time range are / is higher than a predetermined threshold, the base station sends carrier configuration information to the user equipment through the first carrier so the user equipment can configure the second carrier as an auxiliary carrier according to the carrier configuration information. The base station allocates uplink transmission resources on the first carrier and on the second carrier for the user equipment so the user equipment can use both the first carrier and the second carrier to carry out uplink transmission through corresponding configuration. Thus, the user's uplink rate is increased effectively, and the user's uplink rate experience is enhanced under the condition of low design complexity.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a method, device and system for increasing the uplink rate. Background technique

[0002] In the current frequency division of LTE (Long Term Evolution, Long Term Evolution), especially between TD-LTE (Time Division-LTE, Time Division Long Term Evolution) and LTE FDD (Frequency Division Duplexing, Frequency Division Duplexing) frequencies usually need to set a protection band, thereby solving the interference coexistence problem between the two systems. According to the common spectrum allocation scheme at home and abroad, the size of the guard band is usually 5MHz, and in some special scenarios, a guard band of 10MHz or larger needs to be reserved. At present, the spectrum resources of low and medium frequencies are already very tight, and the use of guard bands reduces the available spectrum. Therefore, how to effectively use guard band resources and reduce interference to ad...
